SORUBBlNG-IVICHINE.`

SECIFICATON 'forming part of Letters Patent No.31l,80, dated February 3, 1885.

Application tiled January 23,1884. (No model.)

To LZZ whom, t may concern.'

Beit known that I, JOHN F. CAMERON, a citizen of the United States, residing at New York, in the county of New York and State of New York, have invented certain new and useful Improvements in ScrubbingMachines, of which the following is a description.

This invention relates to that class of scrubloing-maehines which aremountedupon wheels, and which give to one or more scrubbingbrushes a reciprocating motion as they ad- Vance upon the tloor.

The object of my invention is to provide means whereby water may be delivered to the exact point desired; means whereby a brush may be reciprocated to scrub the Hoor; means whereby the surplus dirty water may be gathered from the door, and means whereby the same may be allowed to settle and the clearwater be used again.

To this end my invention consists in the construction and combination of parts hereinafter described and claimed, reference being had to t-he accompanying drawings, in which- Figure 1 is a side elevation, and Fig. 2 is a plan view, of my invention.

A represents the frame of the machine, mounted on four wheels,B, and provided with a handle, O, which may engage the frame at a to pull it by, or at b to push it by.

l) is a shaft journaled in the frame, and provided with belt-pulleys E and cranks F. This shaft receives motion from two of the drivewheels B by means of belts G G and an intermediate speed-increasing pulley H.

I is the serubbingbrush,made thin and Hat to extend completely across the front end of the machine on the door. It is perforated in several places, J, to let water pass down through it.

K K are rods connecting the brush with cranks F, whereby the brush is reciprocated upon the iioor rapidly by the act of advancing the machine. The brush is held upon the door by its own weight and the weight of rods K.

Lis a tank to carry water.

M is a pipe leading from the tank, and provided with a sprinkler head or nozzle, N, which is carried just ahead of the brush, and is provided with holes in the rear side of said nozzle to squirt the water against the front side of the brush, not only to supply water to wet the floor, but to wash away mud that accumulates on the front side of the brush.

O is a wheeljournaled in a yoke, l?, which is hinged at Q to the main frame.

R R are two rollers iournaled in arms f, which are hung upon the hinge-rod Q, and adjustably secured to the yoke l? by means of the arcs g and binding-screws h, in order that the rollers may run on the iioor and support the wheel and yoke,and in order that the yoke may be adjusted to the wear of the buckets.

S represents said buckets, made of llexible materiale-such as rubber-and secured to the wheel O in curves extending rearward from the ends to the middle ofthe wheel on its under side. This wheel is revolved by means of a crossed belt, T, ruiming over a pulley, U, on one of the drive-wheels B. Vheel O revolves in the opposite direction to the drivewheels, in order that it may sweep up the snrplus water and the dirt therein as the machine advances.

V is awater-way hinged at its upper edge to drag its lower edge upon the floor. It is curved in a cylindrical arch tangent to the buckets S, in order that it may guide the water swept up by them into the settling-pan WV. This pan is iixed to the frame of the machine at an angle slightly inclining forward, and it extends the Whole length of the machine to give a broad area for the mud to settle out of the water. Its forward end is perforated above the bottom to allow the clear water to run out, and this front end is located above the brush, that the water may be again delivered at the point needed for use.

X X represent two water-guides, made of rubber,secured each in a head, and provided with a shank, Y, which is fitted tightly in the frame; yet it may be turned to give the rubber guide more or less inclination to the line of travel, and may be raised or lowered to set the rubber more or less firmly on the floor. The purpose of these guides is to turn the water on the iioor into the path of the bucketwheel, to be taken up thereby. The buckets of the wheel are curved to guide the water toward its center, to be carried up the way V with more certainty. The pipe Mis provided with a cock, Z, by means ot' which the flow or" water upon the brush may be regulated or stopped.

ICO

I am aware that scrubbing-machines have tially as shown and described, whereby water 3d been patented showing reciprocating scrub-y bing-brushes,slanting settling-pans,means for raising dirty water from the floor into them, and a revolving wheel having plane radial buckets; and Ido not claim the same,broadl y, as my invention.

What I claim as my invention, and wish to secure by Letters Patent, is-

1. In a scrubbing machine mounted on wheels, having a brush hung at its forward end, and means for reciprocating the same, the combination of a pan hung to the machine and inclined forward, its forward end beingabove the said brush and perforated, and means ,substantially as described,for raising water from the floor into the rearend of the said pan, as shown and described, whereby the same water may be brought forward of the brush and used over again.

2. The combination, in a scrubbing-machine mounted on wheels, and having a settling-pan hung to it, of a wheel journaled in the machine across its rear end, having radial buckets to wipe the door, means for connecting the y said bucket-wheel to the drive-wheel of the machine, with a waterway curved to the are ofthe said buckets, and hung from the pan t0 the floor tangent. to the said buckets, substanmay be wiped bythe bucket-wheel from the floor-all the way into the pan.

3. In a scrubbing machine mounted on wheels, and having a settling-pan hungthereto, the combination of a curved water-way hung to said pan to touch the floor, with a wheel having radial buckets curved backward from the edges to the center,and hung tangent to the said curved water-way, as shown and described.

4L. The combination, in a scrubbing-machine mounted on wheels,ot' a settlingpan,av waterway leading thereto, a bucket-wheel, and side waterguides, and means for adjusting them, substantially as described, whereby they may be set at any desired angle with the line of travel, and with any degree of pressure upon the door.

5. The combination,in a scrubbing-1nacl1ine mounted on wheels,of a settling-pan,a watervWay leading thereto, a bucket-wheel journaled in a yoke hung by hinges to the frame of the machine, and independent rollers adjustably hung to said yoke, as shown and described. JOHN F. CAMERON. NVitnesses: v
